@jdries Has someone thought about generating QLR or QGS files? These could be generated from back-ends or clients and then be used to very simply open the results in QGIS...

QLR seems best suited, but it is (in my case?) not properly set up on Windows to execute QGIS automatically... See also issue qgis/QGIS#45479

I've experimented with it a bit in the Web Editor and was able to generate QGS files, but they need a number of metadata values (e.g. min/max values, extent in projection unit [e.g. meters], ...) that I would need to get from the back-end, otherwise, the QGS import is not very useful and also not user-friendly.

Overall, this would probably be the better solution long-term: qgis/QGIS#45018

@Bart92 I believe you have a gif that shows this as an animation, can you update the Python docs accordingly to show it. I believe it's best to do it in two locations:
https://docs.openeo.cloud/getting-started/python/#batch-job-execution
https://open-eo.github.io/openeo-python-client/batch_jobs.html

In the GIF, we start from the notebook view. Can you also point to the web editor as an option to manage batch jobs?

Resolving this would close SRR2 RID-15

See also the related issue #27 which I'll add for all clients generally

Already solved, see #27. It solves RID-16.
